Symptoms of thrush in an adult may include: 1  A burning feeling in the mouth and throat (at the start of a thrush infection). 2  White patches that stick to the mouth and tongue. 3  A bad taste in the mouth or difficulty tasting foods.
White, cream-coloured, or yellow spots in the mouth. The spots are slightly raised. There is normally no pain in the area underneath the spots. If you scrape off these spots, they leave small wounds that bleed slightly. In adults, thrush can cause an uncomfortable burning sensation in the mouth and throat.
